Yes, we have detailed 3D maps of large portions of the universe, revealing its structure of galaxies, clusters, and voids, built from projects like DESI and COSMOS-Web using data from telescopes like JWST, showing structures from the early universe up to billions of light-years away, though mapping every object remains impossible due to vastness and distance.
About 95% of the universe is "invisible" because it's composed of dark matter (around 27%) and dark energy (around 68%), which don't emit, absorb, or reflect light, unlike the normal matter (stars, planets, us) that makes up the visible 5%. Dark matter's presence is inferred through its gravitational pull on visible galaxies, while dark energy is a mysterious force causing the universe's accelerated expansion.
Leaving the galaxy far enough to photograph it is a whole different undertaking for a species that has not yet left the Solar System. "To get [images of the Milky Way] a spacecraft would have to travel either up or down from the disk of the Milky Way, and travel so incredibly far," Doten explains.
Astronomers using the Hubble Space Telescope assembled a comprehensive picture of the evolving universe – among the most colorful deep... Using data from NASA's Fermi Gamma-ray Space Telescope, scientists discovered a gigantic, mysterious structure in our galaxy.
About the Map
Because light in the universe only travels at a fixed speed we see objects at the edge of the universe when it was very young up to 15 billion years ago. The universe has been partially mapped out to about 2 billion light years.
Hebrews 11 declares that “that the universe was formed at God's command, so that what is seen was not made out of what was visible”. The God of the Bible introduced himself to Moses (Exodus 3) as “I am the one who exists” and Jesus said (John 14) “I am the Truth”.
Yes, when you look at the Sun, you see it as it was about 8 minutes ago because light travels at a finite speed, taking roughly 8.3 minutes to cover the distance from the Sun to Earth, acting like a cosmic time machine, showing us the past of all celestial objects. This means if the Sun vanished, we wouldn't know for 8 minutes, and it also applies to everything else in space, with farther objects showing us even older history.
These are the first words in the Bible: “In the beginning God created the heavens and the earth” (Genesis 1:1). Everything that exists has been created by God. This means the full expanse of the universe was created by God.
Space, or outer space, is a vast, near-perfect vacuum largely devoid of matter. This vacuum contains very few particles compared with Earth's atmosphere. However, it's not entirely empty. Space is dotted with scattered matter called the interstellar medium, which includes hydrogen and helium atoms.
There is consensus that supermassive black holes exist in the centres of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.
Galaxies will “disappear” from reach: They won't vanish, but their light will get stretched so much by the expansion of space that it will become undetectable.
These are photos that NASA chose to send to aliens. They're riding on the first spacecrafts to leave our solar system, Voyager 1 and 2, which are now way out into interstellar space carrying golden records with these images on them.
As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in vacuum in one Julian year (365.25 days). Despite its inclusion of the word "year", the term is not a unit of time.
Dark energy is the name scientists have given to whatever is causing our universe to expand at an accelerating rate over time — another cosmic mystery. Dark energy isn't concentrated in galaxies or galaxy clusters, instead scientists think it's spread throughout the universe.
In 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
But eventually, the lack of oxygen will take its toll. One by one, your major organs will shut down. After only a handful of minutes you will suffer complete organ failure, otherwise known in the medical community as death.
The pain experience reported by both astronauts aligns with previous findings in astronauts exposed to microgravity. The term “space adaptation pain” is used to describe the acute onset of low back pain occurring within the first 24–48 hours of exposure to microgravity, lasting for 9–15 days.
Return to the Moon
Artemis II, scheduled for launch between February and April sees the return of the first people to the Moon since Apollo 17 in 1972. Three American and one Canadian astronaut will orbit the Moon on a 10 day journey that lays the foundation for lunar landings in the coming years.
God is the creator of everything. Everything that exists was created by God. Other worlds exist therefore they were created by God.
John 16:33 means that while followers of Jesus will face hardship, suffering, and tribulation in the world, they can find inner peace and courage because Jesus has already conquered sin, death, and evil ("overcome the world"), and His Spirit lives within them, offering victory and hope amidst their struggles. It's a promise of spiritual triumph over worldly troubles, not an absence of them.
Allah decided to create the universe. Allah, with unlimited power and authority, commanded things to come into being. Allah then made all living creatures, the angels, the planets and the rain to allow vegetation to grow. Allah sent angels to Earth to collect seven handfuls of soil, all of different colours.
Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space. Since there is virtually nothing in space to scatter or re-radiate the light to our eye, we see no part of the light and the sky appears to be black.
Our Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It's about 93 million miles (150 million kilometers) from Earth and it's our solar system's only star.
1 hour on Earth can equal 7 years in space (or vice versa) due to time dilation, a concept from Einstein's relativity where strong gravity or extreme speeds slow down time relative to an outside observer, famously depicted in the movie Interstellar on a planet near a black hole where an hour for the crew meant years passing on Earth. It's not about speed alone in orbit (ISS astronauts age slightly slower), but about proximity to immense mass, like a black hole, bending spacetime so drastically that time crawls for those nearby compared to time far away.
